Moreover, a very small minority of wikis requires registration to create new pages: en.wiki (since 2005, "as an experiment", because of the Seigenthaler incident), id.wiki, fa.wiki and es.books as of 2011. Note that, based on better social and statistical scrutiny of its effects, the community has decided to stop expansion of this configuration to other wikis, see Limits to configuration changes.

On all wikis, newly registered users editing from the same IP address can't do more than 8 edits per minute all combined (technical details: $wgRateLimits). This can sometimes be a problem if you're creating and/or using several new accounts from a single location (e.g. for workshops).

On most Wikimedia projects, accounts that are more than four days old are considered autoconfirmed. Some exceptions include zhwiki, nowiki and dewikibooks which require 7 days to reach autoconfirmed status.

Additionally, some Wikimedia projects require a certain number of minimum edits an account has before it is autoconfirmed. Such wikis with a high threshold include arwiki, eswiki, zhwiki and wikidatawiki; all of which require a minimum of 50 edits before reaching autoconfirmed status.
